Application filed August 22, 1913.

To all trim/u Z nmy concern.

llc it hnown that we. tiiwiucs L. Hxvnnu and Final) J. lmsic. cit zens of the l niicd States. r ridii r at titratiord and Bridgepo t. l'tf:stltt'tl\'v in the county of i' airliehl and P late oi' ionneeticui. have '(llietl certain new and useful lingirovenieuts in inten nal-tomhizstion Engines, of which the follor. in is a tall, clear, and exact i'lescription, such as wiil enable other skilled in the art to which it appertains to make and use the SIHIIC.

Th s invention relates to methods of coir rertine' the potential energy ol liquid fuels into power, and to engines for converting such energy. and with respect to its more speeilie features the invention relates to the method oi converting the energy of liquid h \'drora|l oii oil i uels nto power. and to internal combustion engines of the four cycle type designed to carry out the. method referred to.

()ne of the. objects of the in\ cut-ion is the provision of a practical method for con rerliuc into power the energy potential in :iuuid ll \"(llt)tftil'l)till and so as to ell'eclively utilize a larger proportion of heat units than has iuu'eto'l'oi'e heen attained.

.\nother object of the invention is to provide an internal "ambustion engine utilizing relatively heavy liqu d fuel and which may he readiiv started without the nec ssity for artilieiai v heating the tuel.

Another obieet ol' tl e. invention is to pro vide a practical engine oi the character dc scrih il adapted to use relatively heavy liquid hydrocarbon fuel, such as kerosene, crude oil, etc. and to avoid the expenditure of energy otherwise consumed in heating such tools prior to their entry into the cylinder.

Another obj" 'l oi the inveinion is the pro vision of an ctii .cnt engine 01 the character (lescribegh of increased power and fuel econway over other engines.

()ther obiects will he in part obvious and in part pointed out hereina ter.

The invention accordingly consists in the several steps and the relation and order ot' one or more of such steps with relation to each of the others thereof. and in the fea tures of coustriwtion. combinations of ele- Specification of Letters Patent.

ments and arrangement of parts, which will be exemplified in the method hereinafter disclosed and the construction hereinafter set forth, and the scope. of the application of each at which will be indicated in the follow int: claims.

in the accompanving drawings, illustrating one embod ment of the invention, and wherein similar referei'ice characters refer to similar parts throughout the several \'ie'.vs,-l"igure 1 represents a side view of an engine and its appurtenances. partly in section; and Figs. and 3 are sectional views of detailed portions ol" the engine, mainly d agramn'iatic. in order to more. clearly disclose the construction and operation.

Referring now more particularly to the drawings, the numeral 1 indicates a cylinder of an internal combustion engine having the customary water jacket 2.

The numeral 3 indicates the crank shaft of the engine, 4. the crank, and 5 the piston rod.

The numeral 6 indicates the cam shaft having cams 7 and 8 disposed, respectively, opposite valve. rods 9 and .10, which latter are mounted in suitable guides on the side of the cylinder, and at their upper ends are provided with valves 11 and 12, the former controlling an air inlet port, or opening, 13 leading into the cylinder, and the latter an exhaust opening 14-. through which the products of combustion are ejected from the cylinder, whence they are conducted away through a suitable pipe 14.

I5 indi ates a carhureter, which may be of any approved type, depending in a measure upon the character of oil employed and the manner of its introduction into the engine cylinders. but preferably said carburetor is a suction carburetor provided with an air inlet passage 15 into which the fuel nozzles discharge and through which air passes and on its passage entrains oil in the usual manner.

17 indicates a pipe connecting the carbu rotor with the engine cylinder and through which the aton'iized oil and air from the carburetor pass to said cylinder, and 18 is a check valve adapted to be opened by suction when the force of suction is sufiicient, in order that the carbureted air may be glues devices engine, timed its 1. at pro whore suit zilyto cause the to i'novc down. urdiy against iis spring, whereupon. carimrsted air will be drawn into the cylinder upon the suction stroke, and at a grcuier rate of speed than the air through said inlet.
